SPECIFICATION forming part of Letters Patent No. 699,747, dated May 13,1902.

Application filed October 9, 1901. Serial No. 78,128. (No model.)

To atZZ whom, it may concern:

Be it known thatI, FRED IVL'DE LAPP, a citizen of the United States,residing at Chicago, Cook county, Illinois, have invented a new anduseful Improvement in Railway-Track Lubricators, of which the followingis a specification.

This invention is designed to provide a means for lubricating therailway-track rails by a discharge of water from the tank upon the railswhich shall at all times be under the control of the engineer in thecab. The object of wetting the rails immediately in the rear of theengine or locomotive is to reduce the strain on the motive power,especially when rounding curves, and to a limited extent reduce the wearon the wheels when the brake is applied by reducing the friction, aswhen the wheels slide on the rails. This is accomplished by means of asteam-pipe connected with the head of the boiler, which ex tends fromthe cab to the rear of the forward wheels of the tank-car. A T connectsthis pipe with the injector on the engine, provided with a valve, andabove this latter connection in the steam-pipe is another valve. Asiphon or suction-valve is provided in the steam-pipe at the Tconnection. The engineer by turning on the valve in the steam-pipe andopening the valve in the T draws the water from the injector, which isforced down and sprayed upon the rails.

The method of construction is shown in the drawings, in which- Figure 1is a side elevation of alocomotive with a portion of the cab removed,showing the device attached to boiler-head. Fig. 2 is an enlarged viewof the forked dischargepipe which delivers water to the track-rails.Fig. 3 is an enlarged view of the connectingvalves.

In the construction Fig. 1 shows the side of the cab of the engineremoved to expose the device attached to the head of the boiler A. Theinjector-pipe a, connecting the boiler with the tank-car or tender B inthe usual manner, is also shown. A pipe f is inserted into the top ofthe boiler, as shown, and carried downward parallel with theinjector-pipe a and is extended rearward by means of the flexiblecoupling 'n underneath the center of the forward truck of the tender B,where it is provided with a forked terminal m, with a nozzle over eachof the rails. A valve 0 is inserted in the pipe f within easyreach ofthe engineer in the cab. A suction-valve or siphon d is operativelyconnected with the pipe f beneath the valve 0, and a T i connects thesuction valve d with the injector pipe a. This T 11 is also providedwith a valve e. The suction-valve or siphon d and the T 2' may be castin one piece. The forked tube or termi-' nal for the pipe f is flattenedat the nozzle 0 to spread the Water, so that the object of the inventionmay not be defeated by the swaying of the car, and to avoid uselesswaste of water, which is an important feature on railway-trains.

In operation the valves 0 and e are opened, when the steam from the pipefentersthe suction-valve d. The water is drawn from the injector-pipe aand forced down the tube f and discharged from the nozzles o and spreadupon the track-rails.

Having thus described my invention, while I am aware that railway-trackrails have heretofore been lubricated by water from the ten der, what Iclaim as new, and desire to protect by Letters Patent, is-- 1. In alubricator for railway-rails the com bination with an injector-pipe of asteam-pipe, inserted into the head of the boiler and extending downwardunderneath the cab and to the truck of the tender, a suction-valve insaid pipe, a T connecting said suction-valve with said injector-pipe andvalves to operate said lubricator substantially as specified.

2. In a lubricator for track-rails a steam-induction pipe connected withthe head of boiler of the engine asuction-valve connecting with saidinduction-pipe, a T connecting said suction-valve with thewater-injector pipe on the boiler of the engine and means to operatesaid device substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

FRED M. DE LAPP.
